-module(action_wires_script).
-moduledoc("
This action executes JavaScript directly. It can be used to interface with non-Zotonic JavaScript libraries and functions.

Example:


```erlang
{% button text=\"hello\" action={script script=\"alert('hello world')\"} %}
```

Clicking on the button will show a JavaScript alert with the text hello world in it.

Using template variables:


```erlang
{% with \"world\" as recipient %}
    {% button
        text=\"hello\"
        action={
            script
            script=\"alert('hello \" ++ recipient ++ \"')\"
        }
    %}
{% endwith %}
```
